Theoretical & Experimental Probability

Front

What is theoretical probability?

Back

Theoretical probability is the likelihood of an event happening based on all possible outcomes, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is experimental probability?

Back

Experimental probability is the likelihood of an event happening based on actual experiments or trials, calculated as the number of times the event occurs divided by the total number of trials.

Front

How do you calculate the probability of an event?

Back

Probability of an event = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

If a coin is flipped, what is the theoretical probability of getting heads?

Back

1/2 or 50%.

Front

If a die is rolled, what is the theoretical probability of rolling a 3?

Back

1/6.

Front

Sarah hit the ball 3 times out of 8. What is her experimental probability of hitting the ball next as a fraction?

Back

3/8.

Front

Jon made 15 out of 35 free throws. What is his experimental probability as a fraction?

Back

3/7.

Front

Jill rolled a '5' fifteen times out of 20 rolls. What is her experimental probability as a simplified fraction?

Back

3/4.

Front

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on expected outcomes, while experimental probability is based on actual results from trials.

Front

What is the formula to convert experimental probability to a percentage?

Back

(Experimental Probability) x 100 = Percentage.
